A crocheted representation of Sidneyia inexpectans, one of the more crochetable fossils from the Burgess Shale. See more info from the Smithsonian. This is the first of the toys for children of geeky parents that my son can expect during his life.

This is the 3rd Sidneyia, and the most complete - the previous, incompete specimen lack eyes and feelers.

I used a B or C hook.
